WALTER S. KEYSER, OF EVERETT, WASHINGTON.

HEATING-DRUM To all whom it may concern:

Be it known that I, WALTER S. KEYSER, a cltizen of the Unlted States, residing at Everett, 1n the county of Snohom1sh and 1tt fld l' t l ='l r, a e 0 as nng on, two mventec certain new and useful ln'iprovements in Heating- Drums, of which the following is a specifia cone or deflector, the purpose of which will be hereinafter described.

One of the objects of the invention is to retain or throw the heat downwardly or in other words, to prevent the heat from immediately rising to the ceiling as is the case in other devices of this character.

Another in'iportant feature of the invention is the arrangement and the simplicity of construction of the cone members or deflecting members.

The invention will be more fully understood by reference to the detailed description and drawings connected hereto, the different parts of the invention being designated by reference characters.

In the drawings: Figure l is a vertical, longitudinal sectional view of the complete heating drum with all parts in position. Fig. 2 is a transverse cross sectional view taken on line 2-2 of Fig. 1 and Fig. 3 is a similar view taken on line 33 of Fig. 1.

Let the numeral 5 designate the base of the apparatus which is intended to be suitably connected to a stove or heating apparatus (not here shown), the base being provided with openings 6 through which the air passes to the drum 7. The drum 7 is preferably made in a cylindrical form and is provided at its lower extremity with openings 8 through which pass fastening devices 9 for the purpose of securely mounting the said drum 7 upon the base 5. The base 5 is provided with an opening 10 of a diameter slightly smaller than the inner diameter of the drum 7, thereby leaving a ledge or projection 12 upon which the cylinder 7 may rest. The base 5 is also provided with an u nvardly projecting flange 13 which surrounds the lower extremity of the drum, and acts as a brace to keep the drum in a vertical position. This flange 13 is provided with.

openings 1% which coincide with the openings 8 formed in the drum 7, and are adapted to receive the fastening devices 9. In this way, there is no possible chance of the drum being dislocated or being moved.

The upper extremity of the drum 7 provided with a flange or deflecting member 15. This member is provided with clownwardly projecting ledges 16 and 17 forming a groove 18 into which fits the upper extremity of the drum 7. The ledge 16 projects downwardly a conside able distance farther than the ledge 17 and is provided with openings 18 which coincide with openings 20 formed in the drum 7 for the purpose of receiving the fastening devices 21. in this way the member 15 is securely fastened to the upper extremity of'the drum 7. The member 15 is also provided with an upwardly projecting ledge 22, forming an annular shoulder for the reception of the top c3, this top being provided with an opening for the reception of a bolt 2st, the other ixtremity of the bolt being connected with a cross bar 25 integral with the member 15. This bolt jnrovides a fastening means for securing the top in place.

The drum 7 is divided into two heat retaining compartments 26 and 27 respectively which are separated by a disk 28 provided with aperttued lugs 29 through which apertures pass fastening devices 230 for securing the disk 28 to the drum 7. The fastening devices 1:30 also pass through apertures formed in the drum. The disk 28 is also provided with openings 3i arranged in circular form and which afford communication between the two compartments 26 and 27. The lower compartment has i'nounted therein a cone member 32 which acts as a heat retaining device or deflector. This cone member 32 is preferably composed of sheet metal, but may also be formed of any other suitable material. The base of the cone 32 is provided with downwardly projecting apertured lugs 33, the apertures coinciding with apertures formed in the drum 7 through which pass suitable fastening devices 3 1 for securing the drum in its proper place. The upper compartment 27 has mounted therein a hollow cone member which is of the same construction as the member 32 and is fastened to the drum 7 in a similar way, the only difference of the two cones is that the cone 35 is inverted or has its base facing in a direction opposite to that of the cone 32.

The drum 7 is provided with a series of openings 36 arranged in a transverse circle intermediate the cone 35 and the upper eX- tremity of the said drum. The function of these openings 86 will be described later.

In operation of the device, the heated air passes into the lower portion of the com partment 26 where it is retained or held and allowed to circulate. It then passes into the upper portion of the compartment 26 and it is also retained therein, the cone acting to deflect the heated air and: retain it in the lower portion of the compartment 26 while the disk 28 acts in the same way to retain the heated air in the upper portion of the compartment. After the heated air has been held in the upper and lower portions of the compartment 26 and allowed to circulate therein for a while, it then passes through the openings 31 formed in the disk 28, into the lower portion of the compartment 27 where it is retained by means of the deflector or cone 85, and allowed to circulate. The heated air then passes through the cone 35 into the upper portion of the compartment 27 where it is held and caused to circulate for a limited time, after which it finds its way through the openings 36 and is deflected by the member 15. The deflector 15 prevents the heated air from immediately rising to the ceiling.

It must be understood that the cone members and the different deflectors may be made in various forms and that the drum 7 may also be varied in construction, as by forming it into two or more sections. It may also be stated that. the particular way in which the drum is fastened to the base or the top may also be varied as having the members threaded instead of being bolted as herein shown. The deflecting members may also be fastened to the drum in different ways. These variations are set forth to indicate that applicant not only claims a special construction herein shown and described, but also any modifications thereof which come within the sphere of the invention.

I claim 1. A heating drum consisting of a base having air inlet openings, a drum mounted on said base, oppositely disposed cones secured within said drum said cones having their vertices arranged toward each other but a distance apart, and a separating disk between said cones and having openings affording communication between the compartments upon opposite sides of the disk.

2. A heating drum consisting of a base having air inlet openings, a drum mounted on said. base, oppositely disposed cones secured within said drum said cones having their vertices arranged toward each other but a distance apart, and a separating disk between said cones and having openings aifording' connnunication between the compartments upon opposite sides of the disk, and an exterior air deflector on said cylinder above the uppermost cone.

8. A heating drum consisting of a base I having air inlet openings, a drum mounted on said base, oppositely disposed cones secured within said drum said cones having their vertices arranged toward each other but a distance apart, and a separating disk between said cones and having openings affording communication between the compartments upon opposite sides of the disk, and an exterior air deflector 011 said cylinder above the uppermost cone, said cylinder being provided with air outlet openings between the upper cone and said deflector.

at. A heating drum consisting of a base having air inlet openings, a drum secured to and rising from said base, oppositely disposed eones within said drum said cones having their vertices arranged toward each other but a distance apart, a separating part within the drum between said cones and having perforations near its outer edge, said drum having openings near its upper end, a deflecting member secured exterior to the upper end of the drum above said openings and having an annular shoulder and a top engaging said shoulder, and means for securing said top in position.

5. The herein described heating drum, consisting of the base having the air inlet openings, and a vertical annular flange, the heating drum fitting and secured within said flange and provided with air outlet openings near the top, the dome having the flanged portion secured to the top of the drum, the centrally disposed disk provided with openings and having the ears for securing the disk to the drum, and the oppositely disposed pair of cones arranged above and below the disk with their vertices pointed toward itand having the lugs for securing the disks to the drum.

6. In a heating drum, the combination vith a base having air-inlet openings, a drum mounted on said base having openings formed therein near the top thereof, a disk arranged centrally of the drum in a horizontal position dividing the drum into two compartments, openings in the disk forming connection between the two compartments, a cone secured in the lower compartment and an inverted cone secured in the upper compartment below the openings in the drum and an exterior air deflector on the drum above said openings.

In testimony whereof I afflx my signature, in presence of two witnesses.
